Smart cities: Tech used to live with Alzheimer's

As sensor technology becomes ever more affordable, many people are using it to create smart homes. Most use it for security purposes, or to allow them to control appliances from a distance.

But a pilot scheme in Norway is looking at how a smart home powered by sensors could be used to make homes more manageable for people struggling to adjust to Alzheimer's Disease.

Helge and Kari Farsund are among 25 people trialling the new technology, in their home in the outskirts of Oslo. Created by healthcare firm Abilia, the system combines a central memo planner with sensors around the house.

With an ageing population in the developed world, will more and more of us need to live this way?
